Default Speedometer gears for 3.54 rear ratio- C4

I have a 1991 that is stock ( 275/40 ZR 17 stock tires ) and I installed a 3.54 ring and pinion. I am trying to find out the two speedo gears inside my 700R4. Can anyone help with GM part #'s or tooth counts? Thanks!! :chevy

Thanks for the info!!! I looked at the page listed above ( ... Speedometergearshtm...) and I couldn't figure out how you knew the drive gear, the driven gear and the vehicle speed sensor. How did you do it? Thanks again!!!

For auto there are 2 different VSS; which one used depends on how many teeth the driven gear has. (Off the top of my head) one is for driven gear 41-45 teeth and the other is for 35-40 teeth. In 1991-3, the 6 speed and auto use different VSS. So I picked the auto VSS for the appopriate number of teeth (41-45 totth VSS)
